Why did Hitler want a race of blonde hair and blue eyes when he didnt have blonde hair and blue eyes?

During the 1800s, there arose a notion of an "Aryan race," those who spoke Indo-European languages, who were considered to be responsible for all the progress that mankind had made and who were also morally superior to "Semites," "yellows," and "blacks." The Germanic peoples came to be regarded as the purest "Aryans."This notion, which had been repudiated by anthropologists by the second quarter of the 20th century, was seized upon by Adolf Hitler and the Nazis and made the basis of the German government policy of exterminating Jews, Gypsies, and other "non-Aryans."

Hitler regarded the Nordic Aryans as the only creative race on earth, the only source of human greatness and progress. He believed that its end would mean the end of all civilization. Since he saw the German Reich as the highest expression of Aryanism, he proclaimed that it was necessary, not only for Germany but for the salvation of mankind, to secure the victorious survival of Germany by maintaining the purity of German "blood" against contamination by inferior races.

Note also that Hitler did have blue eyes.
